Why is this sequence $1, 30, 105, 248, 264, 714, \ldots$ not in OEIS?
I got that sequence from this ProofWiki link.
I also did some further searching via Google and found these two papers in the JOURNAL OF INTEGER SEQUENCES:
On the Ratio of the Sum of Divisors and Euler’s Totient Function I
On the Ratio of the Sum of Divisors and Euler's Totient Function II
Just as Lord Shark the Unknown commented, it could be a good idea you submit it to $OEIS$.
For the fun of it, I computed the next terms which are $$1,14,30,105,248,264,418,714,1485,3080,3135,3596,3828,3956,4064,5396,6678,8636,10098,12648,20026,20790,21318,22152,23374,24882,25714,26048,35074,35343,39105,41656,43890,44660,49938,55154,56134,56536,61344,71145,74613,86304,87087,94944$$
