WebNov 12, 2013 · Khan Academy Cryptology Challenge. Couple hints: Polybius square. The messages (besides the very first one) always start with _ _ _ _ _, so fill in those letters. Say the first is P (which it really isn't, but…) and the first “number”, which has two digits, is 34. Therefore, 34, or (3, 4) in coordinates, is P. Fill in from there. WebDeﬁnition 3. A FIELD is a set F which is closed under two operations + and × such that (1) F is an abelian group under + and (2) F −{0} (the set F without the additive identity 0) is an abelian group under ×. Examples: Z/pZ is a ﬁeld, since Z/pZ is an additive group and (Z/pZ) − {0} = (Z/pZ)× is a group under multiplication. howard zimmet obituary
