OEIS Sequences

Primes of the form 36·k² - 810·k + 2753, listed in order of increasing parameter k >= 0. A50268

a(1) = 2; a(2n) = smallest prime starting (the most significant digits) with a(2n-1) (i.e., as a right concatenation of a(2n-1) and a number with no insignificant zeros); a(2n+1) = smallest prime ending in (the least significant digits) a(2n-1). Alternate left and right concatenation yielding primes. A69614

Primes with every digit a prime and the sum of the digits a prime. A62088

Primes that contain only the digits (2, 3, 7). A214704

a(n) = 36·n² - 810·n + 2753, producing the conjectured record number of 45 primes in a contiguous range of n for quadratic polynomials, i.e., abs(a(n)) is prime for 0 <= n < 44. A117081

A monotonic doubly-fractal sequence. Erase the last (rightmost) digit of every integer: what is left is the sequence itself. The erased digits, one by one, form also the sequence itself. A127204

Number of disconnected 3-regular simple graphs on 2n vertices with girth at least 7. A185237

Primes of the form 36·n² - 810·n + 2753, n >= 0, sorted. A22464

Primes that are either single-digit primes or a concatenation of two earlier terms. A104179

Number of disconnected 3-regular simple graphs on 2n vertices with girth exactly 7. A185037
