This is a metaticket listing '''existing''' functions for which symbolic
implementations are urgently needed because
* they exist in Sympy, Maxima, or Fricas symbolically, and might be
returned as result
* they belong to the holonomic repertoire
special:
* Airy functions (#12455)
* elliptic modular j-function (#15354)
* Kummer confluent hypergeometric functions (#14896)
* spherical Bessel and Hankel functions (#15024)
combinatorial:
* Bell numbers
* Bernoulli numbers
* Catalan numbers
* Fibonacci(n), general Lucas(u,v)
* subfactorial
polynomial (metaticket #16670):
* Legendre P,Q (#16813)
* Laguerre (#17151)
* GegenbauerC
* HermiteH
* JacobiP
Also the Dirichlet Eta function which however is not holonomic.
