Smallest Kakeya sets in F_p^5
Find a subset of F_p^5 containing a line in every direction, as small as possible, for 6 primes 5 <= p <= 19. Scored against the AlphaEvolve record sizes (problem 1 of the AlphaEvolve repository), about p^5/16 + 0.4 p^4.

Research brief
# Smallest Kakeya sets in F_p^5
## Goal
A Kakeya set in F_p^5 is a set K that contains a full line `{x + t v : t in F_p}` for every non-zero
direction v ((p^5 - 1)/(p - 1) directions up to scaling). Find one that is as small as possible.
`kakeya.py` exposes
kakeya_set(p: int, d: int, time_budget: float, seed: int) -> list[tuple[int, int, int, int, int]]
`d` is always 5 in this pack (the argument lets one solver serve the F_p^3 and F_p^4 packs too).
Return the points of K as integer 5-tuples; coordinates are reduced mod p and duplicates are
counted once. The eval checks exactly, direction by direction, that K contains a line in every
