Just as I thought SOMA was fading, I heard from Paulo Brina of Belo Horizonte, Brasil.
The story he told was BIG SOMA
Joining the rest of us, SOMA maniacs, Paulo was tired of the old 7 piece soma,
so he began to play Tetra-SOMA, using 4 sets = 28 pieces = 108 cubes.
The tetra set, home made, stainless steel (it's polished, so, it's hard to take photos) |
001 bloc 2x7x9 = 126, so we have 18 holes/gaps . |
002 A 5x5x5 cube would make 125, so we have 17 gaps, 2 are hidden |
003 Another 5x5x5 cube, 1 gap hiden |
004 Converging stairs |
005 Pyramid 9x9 base |
006 Perfect pyramid, my masterpiece, i think |
007 Another pyramid, and a cube |
008 Playing with holes |
009 Only 98 cubes |
010 Only 97 cubes |
011 These chess-board like are funny (and usually hard to arrange) |
012 A perfect one, 108 cubes, . |
013 There are many many geometrical combinations, symetrics are harder |
014 To get symetry, there is a hiden gap . |
015 Interlaced squares, one of multiple possibilities |
016 Another harmonic one |
017 Making it a bit more interesting (where to put the Zs pieces?) |
018 Mandalas are hard . |
019 Another mandala |
020 Isolated cubes are harder to arrange than in lines. |
This is one of the solutions |
Currently only 1 solution exist /SOMA004 ;Paulo 20100325 /............/............/............/............/.....LL..... /............/............/............/............/.....LZ..... /............/............/............/.....aZ...../.....LZ..... /............/............/.....tT...../.....aZ...../.....aa..... /............/.....tT...../.....tT...../.....TT...../.....BA..... /.....PP...../....vPpV..../...vvpPVV.../..ZZBppAZZ../LZZaBBAABZZL /.....Pp...../....Vppv..../...VVPPvv.../..aaApPbBB../LLLaAAbbBLLL /............/.....Tt...../.....Tt...../.....TT...../.....Ab..... /............/............/.....Tt...../.....BZ...../.....BB..... /............/............/............/.....BZ...../.....LZ..... /............/............/............/............/.....LZ..... /............/............/............/............/.....LL.....
