Another common situation is when a(1) differs but all the other terms
are the same, due to different approaches in handling 1's unique
qualities. Some people know enough to start their entry in the search
box with a(2) or even a(3), but there will certainly be others who put
start with a(1) and it would certainly benefit them to get a result
with a cross-reference to the sequence with the different a(1).
