Pythagorean triangle(a,b,c) such that a, c-b, c+b are cubes

 
 

Pythagorean triangle   (a, b, c)   such that

a,    c + b,    c - b   are integral cubes,   say

a \; = \; p^3
c \; + \; b \; = \; m^3
c \; - \; b \; = \; n^3

Then    c^2 \; - \; b^2 \; = \; a^2    gives    m \,n \; = \; p^2

 
Find such Pythagorean triangles
