Alternating-group monodromy conjecture for minimal [1,1]-origamis
A minimal -origami in has squares, and its monodromy group is a subgroup of the alternating group on these squares. The -origamis considered in Theorem~ are the minimal -origamis constructed by Aougab-Menasco-Nieland and their generalisations.
Alternating-group monodromy conjecture. All of the -origamis in Theorem~ have monodromy group isomorphic to .
The theorem cited in the statement leaves open whether the monodromy group is alternating or projective special linear; this conjecture, based on computer experiments, predicts that the alternating case always occurs. The number of squares, , lies below the threshold in a result cited by the authors that would force the monodromy group to contain the alternating group.
