भामिनि O beautiful woman, प्रत्यासन्नक्रमेणापि in order of birth also, राज्यक्रम: succession to the kingdom, भरतस्यैव is for Bharata only, कनीयसो: younger ones, तयो: तावत् for both of them, विप्रकृष्ट: is remote.
O beautiful lady in order of birth, too, Bharata's right to the throne is just next (to Rama's). While being younger, the chances of the other two (Lakshmana and Satrughna) are remote.
