using Robert Gerbicz's seeker.c [1] [2] (modified for speed version) i looked for inter-oeis relations involving 3 sequences. results:

in about 90 minutes, about 50 000 sequence analyzed on a singe core:

167284 relations found (sic, false positives)

the first 30 terms of pruned "stripped" file were used, a lot of false positives due to insufficient number of terms.

the database in oeis format is at:

searchable web interface:

(use +Anumber to search for a sequence)

search for the primes:

search for euler_phi:

some random results (might be wrong):

%F A108954 =A000010-A077150 
%F A000040 =A090417-A031165
