T4 Specialist-knownMilestone (age 18)
At age 17, proved Bertrand's postulate for Carmichael numbers, resolving a 1994 conjecture of Alford, Granville, and Pomerance, while still a high school student.
Larsen grew up in Bloomington, Indiana with both parents serving as mathematics professors at Indiana University. His father hosted a math circle that Larsen attended from age four. After watching a documentary about Yitang Zhang, he became interested in number theory and, after roughly 300 hours of work, proved a result about Carmichael numbers that had eluded mathematicians for decades.

Question four · where did the leverage come from?
Daniel Larsen's leverage provenance
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.

No decisive linked signal
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Daniel Larsen's outcome attributable to any origin.
Luck is not a leftover score.Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Within Researchers / independent engineers, Daniel Larsen's starting-advantage total is at the 74th percentile. Separately, their built or converted leverage total is at the 38th percentile. Other T4 profiles average 5.7 / 24 starting advantage and 10.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary
Larsen's both parents are mathematics professors at Indiana University, providing an exceptionally strong family-domain advantage. His father hosted a math circle that Larsen attended from age four, and his mother is the sister of Fields Medalist Elon Lindenstrauss. He grew up immersed in an academic mathematical household, which gave him direct domain exposure and early mentorship. After watching a documentary about Yitang Zhang, he spent roughly 300 hours proving a result about Carmichael numbers that had eluded mathematicians since 1994, while still in high school.
