A trisquare is a specific type of mathematical object that relates to the concept of squares and triangular numbers. It is defined as a number that can be expressed as the sum of the first ( n ) triangular numbers, which themselves are formed by the formula ( T_n = \frac{n(n+1)}{2} ). This means a trisquare can be represented as ( S_m = T_1 + T_2 + ... + T_m ), where ( S_m ) is the sum of the first ( m ) triangular numbers. Trisquares have interesting properties in number theory and combinatorics.
