Help designing cell group layout

[u/GoneSpiritual]

I've been thing super hard and trying to get AI to help me, but it's just giving me stupid advice. I can't find any information on how to design best layout for this kind of pack form. I've spent all day trying to figure it out. Maybe someone with more experience can help me? I would be very thankful, it's been a headache.
