Inelastic electron scattering is used to identify nine stretched isovector {ital T}{sub {gt}} ({ital T}{sub 0}{r arrow}{ital T}{sub 0}+1) {ital M}6 transitions in {sup 32}S ({ital T}{sub 0}=0) which exhaust (77{plus minus}17)% of the extreme single-particle-hole-model sum rule. This is the first time that several prominent {ital T}{sub {gt}} electromagnetic stretched transitions have been observed in a self-conjugate nucleus and the first time that such a large fraction of the sum rule has been observed. These effects are primarily due to the presence of spectator nucleons in the 2{ital s}{sub 1/2} orbit, as substantiated by shell-model calculations.
