Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(1,2)(3,4)(5,6)(7,9)(8,11)(10,12)(13,14)(15,23)(16,20)(17,21)(18,22)(19,25)(24,28)(26,27);(2,4)(13,15)(14,19)(16,24)(17,25)(18,26)(20,23)(21,27)(22,28);(6,9)(7,12)(10,11)(13,14)(15,23)(16,20)(17,21)(18,22)(19,25)(24,28)(26,27);(13,16,18,17)(14,20,22,21)(15,24,26,25)(19,23,28,27)
