Follow the story. Try a proof. Let curiosity choose how deep you go.
Walk in through the manga: seventeen chapters, sixty-four pocket pebbles, zero required formulas. The Lean source stays behind glass until you ask for it.
Straight to the mathematicsBegin at the proof map — thousands of named theorems — then climb the full ladder from clock inverses to R = T. The story keeps telling itself beside you; it will keep you honest.
Made for company: one reader who loves math and one who does not — one sofa. Whatever each of you finds carries over to the tea salon.
Seventeen chapters, one extraordinary argument. One small discovery is enough for today.
Pip’s rule: mistakes are clues. Every chapter is open, and every question allows another try.

The local hweight establishes 2·index=6 using card_quotient_eq_three and norm_num. CuspForm.norm_eq_zero_iff converts vanishing of the norm, obtained from S6_levelOne_eq_zero′, into vanishing of the underlying function. DFunLike.coe_injective turns the function equality into equality of cusp forms.

Level lowering led to a form that should be nonzero. Now a different result says all forms in the specified space are zero. Keep the space and its conditions fixed; the contradiction requires the same object and conditions.
These links explain the reading route. A story analogy is not a proof of this theorem.

Story → proofThe silent stage means every form in this exact space is zero. It is stronger than failing to find a performer.
Every such form vanishesf = 0Story → proofThree archways stand for the subgroup index. Counting them supplies the factor that changes weight two to weight six.
Count the quotientcard_quotient_eq_threeStory → proofThe transformed stand is also silent because the weight-six, level-one vanishing theorem applies there.
Use the vanishing dependencyS6_levelOne_eq_zero'Story → proofReturning to the original stand means recovering equality of forms from equality of their underlying functions.

Start with the cake-scale story. You only need to read one small piece at a time. If you are in the Fermat story, start with Story depth, then the words listed before the chapter.
You do not need to know Lean, symbols or university mathematics to begin. Definitions come first in the small stories.
Look at the small example before the general formula. Ask what changed and what stayed the same.
Close this panel to return to the exact place you were reading. These are prepared hints for this page.
