a(0) = 0, and for n > 0, (a(n)) gives the indices n for which d(n) > d(k) for k < n, where d is the difference sequence of (cos k + sin k). A299639

a(n) = [ 1/(2·t(n+1) - t(n) - t(n+2)) ], where t(n) = tan(π/2 - 1/n) satisfies n-1 < t(n) < n for all n >= 1. A24817

Values of m such that N = (am+1)(bm+1)(cm+1) is a 3-Carmichael number (A087788), where a,b,c = 1,2,3. A64238
