A fantastical mailbox [1]
Mailbox, (Offset board representation [2]) a square-centric board representation where the encoding of every square resides in a separately addressable memory element, usually an element of an array for random access. The square number, or its file and rank, acts like an address to a post box, which might be empty or may contain one chess piece. As pointed out by Harm Geert Muller, not only the embedded 10x12 board, but various implementations are all mailbox, independently from elements in the array for padding that can act as a sentinel value [3].
