For example, MISTY1 is a Feistel cipher using a three-round Feistel network in its round function, Skipjack is a modified Feistel cipher using a Feistel network in its G permutation, and Threefish (part of Skein) is a non-Feistel block cipher that uses a Feistel-like MIX function.
A gaggle is a term of venery for a flock of geese that is not in flight; in flight, the group can be called a skein.
Largely with the appearance of the eyewitness account of Ginés de Mafra, the only seaman in Magellan's fleet to return to Mazaua, whose testimony reveals a concrete, measurable description of Mazaua, the skein starting from the garbled version of Pigafetta by Ramusio to the mishandling by Combés to Bellin and finally to Amoretti has been unraveled: Pigafetta's Gatighan is Bellin's Limasava.
