Presentation

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

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

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