comb_sum_binomial_row_v1_601307018_4620
A puzzle designer creates a challenge based on a cubic equation: for integers $a$ and $b$ between 1 and 10, how many pairs satisfy $91a^3 - 96a^2b + 48ab^2 - 8b^3 = 40824$? Let $T$ be the count. The designer then builds a number $n = \sum_{k=0}^{T} 3^k$ and raises 2 to this power to get $R = 2^n$, forming the final puz...
