The square of 1529 is the sum of two or more consecutive squares: 15292 = 2337841.
1529 is the number of primitive subsequences of {1, 2, 3, . . . 16, 17}.
1529 is the sum of a positive square and a positive cube in more than one way.
1529 is the 11th term in a sequence defined by the following bilinear recurrence:
Sn+4 Sn = Sn+3 Sn+1 + S2n+2 (n = 1, 2, . . . ) with the initial condition S1 = S2= S3= S4= 1.
This sequence begins 1, 1, 1, 1, 2, 3, 7, 23, 59, 314, 1529, 8209, 833313, 620297, 7869898, . . . .
Interestingly, all the terms are integers even though calculating Sn+4 a priori involves dividing by Sn. This sequence was discovered by Michael Somos and is associated with the arithmetic of elliptic curves.
