Presentation

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

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

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