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