I will also investigate translations and transformations in t-shapes. 1 Basic t-numbers, t-shapes and t-totals A t-shape is 5 cells anywhere on grids in a t shape 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 The t-number is the number at the bottom of the t-shape e.g. 21, 34 and 68 The t-total is where you add up all the numbers in the t-shape e.g. 2+3+4+12+21=42 49+50+51+59+68=276 15+16+17+25+34=97 2 Basic t-formulas This is of a 9x9 grid T-number t-total 57 222 58 227 59 232 60 237 61 242 You can see the t-total in going up 5 every time as the t-number is...
