Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing.

Hints
(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A108237 Erase the odd-indexed digits of the sequence and concatenate what is left. The result is the concatenation of all integers of the sequence. 0

EXAMPLE

Sequence : 11,21,22,31,32,42,43,51,53,62,64,72,74,83,...

To erase :.*..*..*..*..*..*..*..*..*..*..*..*..*..*...

To keep .:..1..1..2..1..2..2..3..1..3..2..4..2..4..3...

leaving .:...11,...21,...22,...31,...32,...42,...43...

so when you concatenate all "kept digits" you get the concatenation of all integers of the original sequence.
