Examples
Triangle starts T(2,1): n\k 1 2 3 4 5 6 7 8 9 10 2: 14 3: 38 48 4: 82 92 116 5: 152 162 186 230 6: 254 264 288 332 402 7: 394 404 428 472 542 644 8: 578 588 612 656 726 828 968 9: 812 822 846 890 960 1062 1202 1386 10: 1102 1112 1136 1180 1250 1352 1492 1676 1910 11: 1454 1464 1488 1532 1602 1704 1844 2028 2262 2552 ... The successive terms are: (2^2 + 1^2 + 2^3 + 1^3), (3^2 + 1^2 + 3^3 + 1^3), (3^2 + 2^2 + 3^3 + 2^3), (4^2 + 1^2 + 4^3 + 1^3), (4^2 + 2^2 + 4^3 + 2^3), (4^2 + 3^2 + 4^3 + 3^3), ... T(7,4) = 472 because 7^2 + 7^3 + 4^2 + 4^3 = 472.
