Cis-block on cuphook is a period-3 oscillator composed of a block stabilising the period-3 cuphook induction coil. This oscillator was found by Rich Schroeppel in October 1970.[1][2] It contains one of only three period-3 three-cell rotors. The others are 1-2-3 and stillater.
Occurrence

This oscillator first appeared naturally on March 15, 2015, in a soup submitted to Catagolue by Adam P. Goucher.[3]
Construction
Cis-block on cuphook is known to be constructible from six gliders, one less than its trans variant.
