Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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