I've unsuccessfully tried to contact Jonathan (see below) on this issue.
So, maybe, somebody else is willing to fix errors in these sequences?

I'm not sure whether the definitions or terms are as intended but they
obviously disagree.

Thanks,
Max

Hi  Jonathan,

Your sequences do A124869 .. A124872 are defined as numerators /
denominators in expansion of
(-1 + i*sqrt(3))^(-n)
but numerical values as well as examples correspond to expansion of
(-1 + i*3)^(-n).

Moreover, there is an error in formula section which specifies the
power as (...)^n not (...)^(-n).

Regards,
Max
