From Polyphasic Sleep Wiki
This variant, which is rarely attempted, has cores of slightly different lengths. These variants allows for slightly more time awake, may be easier to schedule, without a significantly harder adaptation. Other plausible combinations include 3-3.5, or even 4.5-2.5 and 5-1.5. It would be helpful to know the SWS and REM requirements before picking any of these variants, though.
