This is comparable with the 24th square pyramid having a total of 70 2 cannonballs. [5] Similarly, a pentagonal-pyramid version of the cannonball problem to produce a perfect square, would have N = 8, yielding a total of (14 × 14 = ) 196 cannonballs. [6] The only numbers that are simultaneously triangular and square pyramidal are 1, 55, 91 ...
This is known as the cannonball problem, since it can be visualized as the problem of taking a square arrangement of cannonballs on the ground and building a square pyramid out of them. It was not until 1918 that a proof (using elliptic functions ) was found for this remarkable fact, which has relevance to the bosonic string theory in 26 ...
Édouard Lucas found the 4900-ball pyramid with a square number of balls, and in making the cannonball problem more widely known, suggested that it was the only nontrivial solution. [5] After incomplete proofs by Lucas and Claude-Séraphin Moret-Blanc, the first complete proof that no other such numbers exist was given by G. N. Watson in 1918. [6]

Hexagonal close-packing would result in a six-sided pyramid with a hexagonal base. Collections of snowballs arranged in pyramid shape. The front pyramid is hexagonal close-packed and rear is face-centered cubic. The cannonball problem asks which flat square arrangements of cannonballs can be stacked into a square pyramid.
