Protects against heartworms, hookworms, roundworms, whipworms, and flea populations. If the derivation $S \Rightarrow^*W_1W_2\dots W_m$ is leftmost (rightmost) then the sentential form $W_1W_2\dots W_m$ is called left-sentential form (right-sentential form). In addition, if $W_1W_2\dots W_m$ contains only terminal symbols then it is called a sentence. SENTINEL Marvel Fighting Armor Black Panther Action Figure USA Seller. Then the string $W_1W_2\dots W_m$ is a sentential form of a grammar $G$. DC Direct Uni-Formz Modern Green Lantern Limited Edition Designer Vinyl Figure. Assuming you know what leftmost and rightmost derivations are, let $S \Rightarrow^*W_1W_2\dots W_m$ be a derivation (a sequence of replacement using derivation rules), where $W_i$ is a terminal or nonterminal symbol.
