   The object was studied:

https://ui.adsabs.harvard.edu/abs/2014PASJ...66...30K/abstract

Porb = 0.091433(1) (CRTS data, in the period gap)
q = 0.23(1) (from stage A superhumps)

   So it is most likely that multiple rebrightenings
were the result of a system close to the stability
border of the 3:1 resonance.
