Polymerizable compound, polymerizable composition, polymer, and optically anisotropic body

A polymerizable compound represented by a general formula (I),

• wherein Q1 to Q4 are independently a hydrogen atom, or a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms,
• X is a substituted or unsubstituted divalent aromatic group having 6 to 12 carbon atoms,
• Ax and Ay are independently a group represented by a general formula (II),
• wherein “*” indicates a bonding position,
• Y1 to Y6 are independently a chemical single bond, —O—, —S—, —O—C(═O)—, —C(═O)—O—, —O—C(═O)—O—, —NR1—C(═O)—, —C(═O)—NR1—, —O—C(═O)—NR1—, —NR1—C(═O)—O—, —NR1—C(═O)—NR1—, or —NR1—O—, R1 is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms,
• G1 and G2 are independently a substituted or unsubstituted divalent aliphatic group having 1 to 20 carbon atoms that optionally includes —O—, —S—, —O—C(═O)—, —C(═O)—O—, —O—C(═O)—O—, —NR2—C(═O)—, —C(═O)—NR2—, —NR2—, or —C(═O)—, provided that a case where the aliphatic group includes two or more adjacent —O— or —S— is excluded, R2 is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms,
