Frank Ellermann: The video shows the first terms for p(5k+4), and A333435 + A333546 also using this video "stole" the "p(11m+6) == 0 (mod 11)" link for an example.

Frank Ellermann: A333436, it's a pair A333435 + A333436, and the "pink box" needs  preview + undo + edit as accessibility feature for folks like me, who are too old to pass as "boomer" (could be also "only me", because I started 7 of 8 not yet archived https://oeis.org/wiki/OeisWiki_talk:Community_Portal issues.)
