Random Sequencing

[N. J. A. Sloane]

Don't forget the index file!  If you want to
find the A-number for the all-1's sequence,
or the Fibonacci numbers, that 's the fastest way.  For example:

alkyls: A000598 A000639 A000642 A000645 A000646 A000647 A000648 A000649 A000650 A005957 A010372 A022014
 A036996
all-0's sequence: A000004*
all-1's sequence: A000012*
all-2's sequence: A007395*
all-3's sequence: A010701*
all-4's sequence: A010709*
all-5's sequence: A010716*
all-6's sequence: A010722*
all-7's sequence: A010727*
all-8's sequence: A010731*
all-9's sequence: A010734*
almost primes: a k-almost prime has k prime factors, counted with multiplicity: A001358, A014612, A0146
13, A014614
almost-natural numbers: A007376
alphabetical order, numbers in: A000052*
