a(n) = (n+1)⁵ - n⁵. A22521

Primes of form (k+1)⁵ - k⁵ = A022521(k). A121616

Difference of two positive 5th powers. A181124

a(n) = 11ⁿ - 10ⁿ. A16195

a(0)=1, a(1)=1, a(n) = 11·a(n/2) for even n, and a(n) = 10·a((n-1)/2) + a((n+1)/2) for odd n >= 3. A116525

Nonsquare factors k > 0 such that k·x² - 1 produces a new minimum of its Hardy-Littlewood constant. A331948

Quintan primes: p = (x⁵ - y⁵)/(x - y). A2649

Primes p such that π(p) is obtained by dropping one of the digits of p in decimal expansion. A114924

Times on a 12-hour digital clock with 6 digits at which the three continuously moving hands of an analog clock, in the best approximation, enclose the same angles with one another, i.e., have the smallest sum of squares of the deviations from 120 degrees. When interpreting the terms as times of the day in the form hh:mm:ss, padding to the left with zeros is assumed. A347040

Largest prime p(k) > p(n) such that 1/p(n) + 1/p(n+1) + ... + 1/p(k) < 1, where p(n) is the n-th prime. A225671
