Example

gf28Add : {n} (fin n) => [n]GF28 -> GF28
gf28Add ps = sums ! 0
  where sums = [zero] # [  p ^ s | p <- ps | s <- sums ]

• type: function | symbolic_name: gf28Add | examples/AES.cry:37

Use

Statement and proof are available both joined (fact) and split (statement, proof) for proof-term modeling, autoformalization, retrieval, and dependency analysis via deps.
