Pell-Type Number Generators of Pythagorean Triples

1993
It is well-known that primitive Pythagorean triples x, y, z can be generated by external generators M, N according to the equations $$ x = {M^2} - {N^2},\;\;y = 2MN,\,\,z = {M^2} + {N^2} $$ (1.1) where x, y, z, M, N are positive integers, (M, N) = 1 and M + N ≡ l(mod 2).

TRIANGULAR AND SQUARE TRIANGULAR NUMBERS INVOLVING GENERALIZED PELL NUMBERS

2017
Triangular numbers denoted by T-n are the numbers of the form T-n = n(2+1)/2 for n >= 0. There are infinitely many triangular numbers that are also square numbers. These numbers are called square triangular numbers and denoted by S-n. One can write Sn as S-n = s(n)(2) =t(n)(t(n)+1)/2 where s(n) and to denote the sides of the corresponding square and ...
