Appears in sequences

• Take pairs (x,y) with Sum_{j = x..y} j = concatenation of x and y. Sort pairs on y then x. This sequence gives y of each pair.at n=29A070153
• Numbers whose base-10 and base-7 representations are permutations of the same multiset of digits.at n=43A130604
• Semiprimes which are products of two primes each with half the number of digits, and which when split in the middle gives two primes; no leading zeros.at n=32A243749
• Positive numbers k such that the centered cube number k^3 + (k+1)^3 is equal to the difference of two positive cubes and to A352755(n).at n=20A352756
