a(n) = smallest m such that wt(m²) = n (where wt(i) = A000120(i)), or -1 if no such m exists. A231897

Primes p having exactly one partition into distinct divisors of p+1. A85499

Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of the n*(k+1) boundary points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of regions in the resulting planar graph. A367323

a(n) is the least k such that k² has a maximal Hamming weight A357658(n) in the range 2ⁿ <= k² < 2ⁿ⁺¹. A357659

a(n) is the largest k such that k² has a maximal Hamming weight A357658(n) in the range 2ⁿ <= k² < 2ⁿ⁺¹. A357660
