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

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

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