Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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