Mathematician needed to review mathematical content on playing cards for accuracy

I'm developing a premium mathematical playing card deck called Edgewise Cards: First Principles. The deck features 18 featured cards with mathematical content (equations, proofs, notation, and diagrams) spanning calculus, number theory, group theory, orbital mechanics, geodesy, and more. I need a mathematician to review all mathematical content for accuracy before production. This includes: - Verifying all equations are correct and properly notated - Flagging any hallucinated or incorrect mathematical representations - Suggesting corrections where needed - Confirming that historical attributions are mathematically accurate Additionally, 36 number cards each carry a short mathematical fact about their number (4 facts per number, one per suit). These also need verification for accuracy and mathematical soundness. The concept content was developed using AI and has already been flagged for errors by the collector community, so rigor is essential. This deck is intended for mathematically literate collectors and will not ship with wrong equations. Deliverable: a written review of all mathematical content with corrections and recommendations. Estimated scope: 54 cards total, roughly 4-8 hours of work. Happy to share all card designs upfront.
