An aggregator needs to find the index in the sync committee (as returned by `get_sync_committee_indices`) for a given validator referenced by `sync_committee_signature.validator_index` and map the sync committee index to an index in the subcommittee (along with the prior `subcommittee_index`). This index within the subcommittee is the one set in the `Bitvector`. -For example, a validator with index `2044` could be at index `135` in the current sync committee. This sync committee index maps to `subcommittee_index` `1` with position `7` in the `Bitvector` for the contribution. +For example, if a validator with index `2044` is pseudo-randomly sampled to sync committee index `135`. This sync committee index maps to `subcommittee_index` `1` with position `7` in the `Bitvector` for the contribution. Also note that a validator **could be included multiple times** in a given subcommittee such that multiple bits are set for a single `SyncCommitteeSignature`. ###### Signature
