1.1.58 द्विवचने अचि

The अजादेश caused by द्विवचन is done at the place of स्थानी. The द्वित्व itself can be due to एकाचे द्वे प्रथमस्य. In पपतु:, पा पा अतुस् - results in पा प् अतुस् (अजादेश at स्थानी) and becomes पपतु:.

Note that interpretations of the rule differ in महाभाष्य and वैयाकरणसिद्धान्तकौमुदी. The latter assumes that अजादेश should not occur before द्वित्व is performed. The result (at least in these examples) is not affected because of this difference.
