Presentation

minimal degree	μ(G) = 44
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 3 generators on 44 points:

(1,2)(3,4)(5,6,8,10,7,9,11,12)(13,14)(15,23,26,36)(16,20)(17,21)(18,22)(19,25,31,39)(24,35,38,43)(27,32)(28,33)(29,34)(30,37,41,44)(40,42);(6,9)(10,12)(13,15)(14,19,22,31)(16,24)(17,25)(18,26)(20,30,33,41)(21,23,34,36)(27,37)(28,38)(29,39)(32,35,42,43)(40,44);(2,4)(13,16,17,27,18,28,29,40)(14,20,21,32,22,33,34,42)(15,24,25,37,26,38,39,44)(19,30,23,35,31,41,36,43)
