Type constraint

I believe that an item with OEIS code should be one of the following:

• instance of (P31)integer sequence (Q2297602) (for usual integer sequences, like Fibonacci sequence (Q23835349)OEIS ID (P829)A000045),
• subclass of (P279)integer (Q12503) (for number types, like prime number (Q49008)OEIS ID (P829)A000040),
• instance of (P31)real number (Q12916) (for decimal expansions or continuous fractions of real numbers, like pi (Q167)OEIS ID (P829)A000796),
• instance of (P31)real-valued function (Q5189500) (for natural-to-integer functions, like factorial (Q120976)OEIS ID (P829)A000142),

so I added a constraint which allows all of them, but also a bit more: instance or subclass of (Q30208840) + real number (Q12916) or real-valued function (Q5189500) or integer sequence (Q2297602). It would be good if anybody will also add a complex constraint. Wikisaurus (talk) 23:47, 4 December 2019 (UTC)

• Well, I created type of natural numbers (Q77359186); after some cleanup it will probably be possible to replace 2nd condition with instance of (P31)type of natural numbers (Q77359186). Wikisaurus (talk) 00:55, 5 December 2019 (UTC)
