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

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

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