[seqfan] Re: Proposal for better presentation of some sequences with complex numbers

Some time back, I proposed adding F numbers, which would provide a 
standard way to show not only fractions and complex numbers, but also 
irregular tables, two-way infinite sequences, sequences defined on 
fractions and complex numbers, and a number of other things. The 
reaction at the time was underwhelming, but I still think it's a good 
idea. Note that with this proposal, one would be able to search for 
these things as well.

The basic idea is to have a database with definitions, like 
"A000010/A000027". This could include comments, formulae, everything 
except actual values and (in some cases) offsets; the sequence 
contents, including b-file equivalents, would then be automatically 

Implementing this would be a major project, I admit.

Great idea! Maybe you could discuss it with Russ Cox?
