OEIS Sequences

a(n) = n*(13·n² - 7)/6. A62025

For n>0, a(n) is the least quasi-Carmichael number to base -n, extended to n=0 with the least composite squarefree integer. A29591

Lucas pseudoprimes. A217120

a(n) = n*(21·n-17)/2. A226491

Numbers n which are neither palindromes nor the sum of two palindromes, with property that the largest palindrome which when subtracted from n yields the sum of two palindromes is not the palindromic floor of n (A261423(n)), but rather the next palindrome below that. A261911

Expansion of 1/(x^k*(1-x-3·x^k+1)) for k=5. A143456

Odd composite integers m such that U(m)² == 1 (mod m) and V(m) == 4 (mod m), where U(m)=A001353(m) and V(m)=A003500(m) are the m-th generalized Lucas and Pell-Lucas numbers of parameters a=4 and b=1, respectively. A337778
