Floyd's triangle

Floyd's triangle is a right-angled triangular array of natural numbers, used in computer science education. It is named after Robert Floyd. It is defined by filling the rows of the triangle with consecutive numbers, starting with a 1 in the top left corner: Beginning programmers are often assigned the task of writing a program to print out the table in the format shown. Summing up the row sums in Floyd's triangle reveals the doubly triangular numbers (triangular numbers with an index that is triangular)(sequence A002817 in the OEIS) 1 = 1 = T(T(1))
