definition_equality → concludes about Triangle read by rows, T(n,k) = T(n-1,k) + T(n-2,k) + T(n-1,k-1) + T(n-2,k-1) and T(0,0) = 1. JSON

Theorem

Operation

All-n equality of two definitions

{
  "operation": "definition_equality"
}

Premises

None: this step is a direct theorem check.

Claims

Verification and certificate

• polytool: replayed (the certificate replayed when the step was written)
• Lean: not attempted
• certificate: definition_equality, SHA-256 8c10e8f643900fba2c82854959b607434164c59bc1c59cd4263cb31cead934f7, 9,839 bytes (2,679 compressed); download JSON
