Dear Seq Fans, A couple of years ago Brady Haran and I made a video based
on an imaginary conversation with Armand Borel and Freeman Dyson - there is
a link in A173426.  I was wondering if there had been any progress on
finding the next term in the sequence 10, 2446 mentioned in the video, so I
checked all the comments on the video.  There are a lot,  although no
progress on that question.  Still, this led me to create several new
sequences, one of which, A360503, exists because of a comment.

I also created an entry in the OEIS Index to link these sequences
together.  Several of them need more terms.

Here's what is in the Index entry:

Most Wanted Primes video, sequences related to: (closely related sequences
are adjacent)

base 2: A007088, A036952; A058935; A359149, A173427, A300570, A098780,

base 3: A007089, A036954; A360502, A048435, A360503; A360504, A260853;
A360505, A360506, A360507, A360508

base 4: (need help here)

base 10: A000027, A000040; A007908*; A173426*, A359148*; A000422, A176024

others: A019519, A046036; A019518, A046035, A069151; A019523; A260852

I also added a pointer to the index from most of the sequences: the pointer

Primes video</a>

Incidentally, there has been no progress at all on finding the first prime
in A007908, the most basic of all the questions.
