Analyze duplicate token entries in the Solana ecosystem and identify the “original” token (the token created earlier than others with the same name and token symbol.

1. Only take into account tokens created before March 19, 2025.
2. Consider duplicates with different cases (”SSS” is a duplicate of “sss” and “SsS”)
3. Only output duplicates that have at least 50 tokens with the same name and symbol (50 including the original one)
4. Only output top-40 of such tokens with the most recent creation time of the original token

The result should include the following data:

1. Token name and symbol (from the earliest occurrence)
2. First creation timestamp (original token creation time)
3. Last creation timestamp
4. Total number of duplicates (including case variations)
5. Token mint address from the earliest occurrence (original token address)

Solana data:

I recommend using the [tokens_solana.fungible](<https://docs.dune.com/data-catalog/curated/solana/asset-tracking/solana-token-metadata>) table on Dune or similar sources with token data.

Correctness criteria:

The table should be equal to a baseline solution.
