Presentation

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

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

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