It has been suggested that this article or section be merged into Thumb 1 due to the following reason: not sure how this is notable, aside from historically; this information could easily fit as a note on either article (Discuss)
Thumb 1 on queen bee shuttle is a period-90oscillator that is composed of a thumb 1 and a queen bee shuttle. Although it is composed of two oscillators of smaller periods (p9 and p30 respectively), it is considered non-trivial because it contains five cells that oscillate at the full period. In terms of its 56 cells, it was the smallest known non-trivial period 90 oscillator until the discovery of the 45-cellunix on p45 pi-heptomino hassler in 2022.
