• Composite numbers whose prime factors contain no digits other than 1 and 9.at n=27A036309
• a(n) = a(n-1) + a(n-2) + R(a(n-3)) where a(0) = a(1) = a(2) = 1 and R(n) (A004086) means the reverse of n.at n=17A074858
• Number of compositions of n in which the maximal multiplicity of parts equals 10.at n=11A243127
• Self-inverse permutation of natural numbers: a(0) = 0, a(1) = 1, and for n > 1, if A117966(n) < 0, a(n) = A117967(1+a(-(A117966(n)))), otherwise a(n) = A117968(a(A117966(n)-1)).at n=32A246211
