• Alphabetically — the A–Z list below.
• By hierarchy — primes arranged by the typed parent–child relationships of the catalog's directed-acyclic hierarchy. Foundational primes anchor the top; each prime sits under its primary parent, with secondary parents and mutual partners noted inline. Click to expand any subtree.
• By ontology — every prime placed in the canonical category-and-sub-category tree. Best for understanding how the primes are conceptually organized.
• By domain — primes grouped by the intellectual tradition they originate from (Mathematics, Physics, Psychology & Behavioral Sciences, …). Each domain page also lists primes that draw from it as a secondary origin.
• By family — primes grouped by their neighborhood in abstraction space (k-means clusters over structural-signature embeddings), each with a short description. This is the empirical 'which primes sit near each other' view, distinct from the curated category/ontology trees.
• By learnability — primes sequenced as a curriculum, easiest first, with the catalog's prerequisite hierarchy honored. Five tiers; a reading-level toggle (ELI5 / ELI10 / ELI15 / ELI18 / Specialist) swaps every prime's explanation to your chosen level. Best for teachers, curriculum builders, or anyone approaching the catalog as a learner. See the methodology paper for how the tiering was built.
