EULERIAN MAGIC WORD SQUARES

LEONARD GORDON Tucson, Arizona

In the May 1933 Word Ways, Lee S a llow s int rod uc e d a f orm of gematria he called wints (word integ e r s), based o n t he use of t he a lp habet and a space to e x p r ess numbers in base 2 7. (In normal ge mat ria, A=l, B=2, etc.) His article included 3x3 and 4x4 magic squares ma d e f r om wi nts and f o und by com puter search. In May 1996 h e p re s ente d add it i onal 3x3 squares fo u n d by computer search. I n the origi nal article, man y of the magic co ns t a nts were wints. This was not true for the later s e t. Most are simply Euler squares wh ic h become magic f or any gem atria .

An Euler s q u are , a lso known as a Graeco-Latin square, :lS an important tool of statisticians and mat he maticians. As illustrated in F:i g­ure 2, it consi s ts of an n xn array of tw o-digi t num b ers, eac h digi t of which is 0,1,2 ... or (n-l). Eac h units digit appears once in every row a n d once in every colu mn, as does each tens digit; f urthermore, ev e ry possible c ombin a tion of t wo digits is represen t ed (00,01,02 ... (n-l )(n-1». Eulerian s quare s exist for most v alues of n; 6 is a fam o u s exception , proved, as Euler himself conjectured, to be impos s ible.

T h e ten s digits n eed not be 0,1,2 ... ; they ca n be a ny set of distinc t n um bers suc h as 22 ,31,48,921 ,2882 . T he units digits can b e similarly gen­e ralize d , an d n e ed not matc h t he tens d igits; h o weve r t h ey must a ll ha v e t h e s ame n umber of digits. T he construction of Euler wo r d sq uares is based o n this gen eralization.

I now show how to construct Euler word square s using a co mputer strictly as an a n cillary device. I present t wo 5x5 squares f o r which the magic c on stant is a wint; I also present one 8x8 square . To start , I con­structed th e matrix of Figure 1. Startin g with a so mew hat larger array (which was later reduced) and usi ng my word p ro e es s o r as a c h alkboard, I shifted rows and columns to re v eal the region of ma ximum density in the lo wer right. This r egi on includ e s 8 rows an d 7 colu mns . Using the letter-groups end, ill, ore, ins, ear, its, a re, a ll t o re p resent the u nits digits 0,1 ,2,3,4,5,6,7 and the letter-grou p s ->b ,f ,p, t ,w,sh ,s p to represent the tens digits 0,1 ,2,3,4,5,6 ,7. one c onv erts t he 8x8 Euler square in Fig ure 2 to the 8x8 Euler word square in Figure 3. (Since all 3-letter endings are t h e mselves words, the _ as sig n me nt is pos s ible.)

All word s im plied by Figure 1 are i n Merria m- Webster's 10th Collegiate dictionary. Figure 1 allows us to extr a ct many s quare s of v ariou s sizes but it took a full day of t rial an d e rror to find one which wh en t aken as a wint square has a magi c constant which i s also a wint. The ma gic constant for Figure 4 can be fo u nd in An s wers and Solutions.

In his initial article, Sallows asks for a magic is the wint "magic". This required going to the to allow making Figure 5. This square would not computer search even if I had used a vocabulary Sallow s' s.

square whose constant unabridged dictionaries have been found by a many times as large as

have been making arrays like Figure 1 for some time. Sets of begin­ning-ending combinations are useful for many puzzles. Figure 6 was in my notes. Figure 7 is constructed from it. Most of the 7-, 8- and 9-let­ter words come from unabridged dictionaries.

For ordinary gematria, return to Figure 1. These Euler are presented in condensed form:
