Theorem · version 2
Strong BSD would determine Sha’s order from the other invariants
Statement
For an E/Q satisfying strong BSD, #Sha(E/Q) = [L^{(r)}(E,1)/r!] · #E(Q)_tors² / [Ω_E Reg_E ∏_{ℓ finite} c_ℓ(E)], with r = rank E(Q) and the stated full-L and Néron conventions.
Assumptions
- Strong BSD for the particular E/Q, including Sha finiteness.
- Compatible normalizations and certified values of the other inputs are required to recover an exact order.
Scope
An algebraic rearrangement of the conjectural leading-term formula under its premise; approximating an L-value does not certify the integer.

Conditional implication · Proved
Source-grounded deduction from the normalized strong formula, not an independently proved general formula for Sha.
This rearranges the full formula under its premise; numerical approximation alone does not certify the order.
Scope: The leading-term formula would recover Sha’s order from compatible certified invariants.
Limit: The full formula and finiteness remain unproved in general. A decimal comparison alone is insufficient.
A consequence under an open premise, not an additional resolved part of that premise.
Relationship not independently reviewed. This concerns its use in this problem.

Recorded wording
Strong BSD predicts rank equality, finite Sha, and the leading coefficient formula with real period, regulator, Tamagawa factors and torsion.
