There are an infinite number of triangular numbers that are also squares. You can generate such numbers using the formula:
Sn+1 = 4Sn(8Sn + 1)
With the first Sn being 1.
This gives the next such number as:
Sn+1= 4 (8 + 1)
= 36
You can then plug that into the equation to get:
Sn+1 = 4 x 36 (8 x 36 + 1)
= 41616
and so on.
