Dec 19, 2015 at 11:16	comment	added	quintopia		@Mego I worry about your implementation of median if something can be both the median and max in the case that the list isn't all the same number. If you mean "in the middle of the list" then you might choose a different name for it...

Dec 17, 2015 at 17:04	comment	added	quintopia		What? Isn't 2nCn the max of the 2nth row?
Dec 17, 2015 at 3:02	comment	added	user45941		You can save a byte by exploiting the fact that the rows of Pascal's triangle are symmetric, so the median of the `2n`th row is `C(2n,n)`. Thus: `,;u@τ╣║/` for 8 bytes.
