Properties

Appears in sequences

• Primes which are concatenations of four consecutive numbers.at n=1A030471
• Let N = 123456789101112131415... the concatenation of natural numbers; partition this number into minimal strings of noncomposite numbers, i.e., a(1) = 1 and a(2) onwards are primes.at n=9A068661
• Write the natural numbers as an infinite sequence of digits; starting at the left, cut into the smallest pieces so that each piece is a prime.at n=3A103575
• Primes from merging of 8 successive digits in decimal expansion of the Champernowne Constant.at n=3A104951
• Consider the infinite string S = 12345678910111213141516171819202122232425262728293031... Sequence gives the first prime that starts at the k-th digit, skipping zero digits.at n=16A135605
• Write the natural numbers as an infinite sequence of digits; starting at the left, cut into the smallest pieces so that each piece is a prime. Leading zeros are thrown away.at n=3A162324
• Numbers whose decimal expansion is a concatenation of 4 consecutive increasing nonnegative numbers.at n=13A279204
• Write down the positive integers. To obtain the terms of the sequence, concatenate groups of these so that the last number of each concatenated group is a prime.at n=6A367431
• Prime numbersat n=919300
