Theorem 4sqlem11 12724

Description: Lemma for 4sq 12733. Use the pigeonhole principle to show that the sets {𝑚↑2 ∣ 𝑚 ∈ (0...𝑁)} and {-1 − 𝑛↑2 ∣ 𝑛 ∈ (0...𝑁)} have a common element, mod 𝑃. Note that although the conclusion is stated in terms of 𝐴 ∩ ran 𝐹 being nonempty, it is also inhabited by 4sqleminfi 12720 and fin0 6982. (Contributed by Mario Carneiro, 15-Jul-2014.)

Distinct variable groups:   𝑣,𝐴   𝑚,𝑁,𝑢   𝑣,𝑃   𝑃,𝑚,𝑢   𝜑,𝑣   𝜑,𝑚,𝑢

Allowed substitution hints:   𝜑(𝑥,𝑦,𝑧,𝑤,𝑛)   𝐴(𝑥,𝑦,𝑧,𝑤,𝑢,𝑚,𝑛)   𝑃(𝑥,𝑦,𝑧,𝑤,𝑛)   𝑆(𝑥,𝑦,𝑧,𝑤,𝑣,𝑢,𝑚,𝑛)   𝐹(𝑥,𝑦,𝑧,𝑤,𝑣,𝑢,𝑚,𝑛)   𝑁(𝑥,𝑦,𝑧,𝑤,𝑣,𝑛)

Proof of Theorem 4sqlem11

Dummy variable 𝑘 is distinct from all other variables.
