minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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