    <brief>Move four vector registers to four ZA single-vector groups</brief>
    <description>
      <para>The instruction operates on four ZA single-vector groups. The vector numbers forming the single-vector group within each quarter of the ZA array are selected by the sum of the vector select register and immediate offset, modulo quarter the number of ZA array vectors.</para>
      <para>The <arm-defined-word>vector group</arm-defined-word> symbol <syntax>VGx4</syntax> indicates that the instruction operates on four ZA single-vector groups.</para>
      <para>The preferred disassembly syntax uses a 64-bit element size, but an assembler should accept any element size if it is used consistently for all operands. The <arm-defined-word>vector group</arm-defined-word> symbol is preferred for disassembly, but optional in assembler source code.</para>
      <para>This instruction is unpredicated.</para>
