cp's OEIS Frontend

This is a front-end for the Online Encyclopedia of Integer Sequences, made by Christian Perfect. The idea is to provide OEIS entries in non-ancient HTML, and then to think about how they're presented visually. The source code is on GitHub.

A340348 Add the two terms of the first pair of integers to produce b(1); add the two terms of the second pair of integers to produce b(2); add the two terms of the third pair of integers to produce b(3), etc. This sequence and the b(n) sequence share the same succession of digits.

Comments

This is the lexicographically earliest sequence of distinct integers > 0 with this property. The sequence is conjectured to be a permutation of the integers > 0.

Examples

			1 + 109 = 110
2 + 7 = 9
3 + 24 = 27
4 + 28 = 32
5 + 39 = 44
6 + 22 = 28
8 + 45 = 53; etc.
The 3rd column and the starting sequence share the same succession of digits.
