Jianing Song, Table of n, a(n) for n = 1..307 (all terms <= 1500)
EXAMPLE
1/5^2 + 1/35^2 = 1/7^2 + 1/7^2, so 35 is a term.
1/10^2 + 1/55^2 = 1/11^2 + 1/22^2, so 55 is a term.

(PARI) isA355812(n) = for(p=1, n-1, for(q=1, n-1, r=1/(1/p^2+1/q^2-1/n^2); if(r==r\1 && issquare(r), return(1)))); return(0)
