Hi,

Accts is list not map So got the value from List you need to pass the index in Number not in ID. Like below 
{!a.id}............... {!accts[1].name} <br/><br/>

Option 1:- Value from List
Try below code if you want to get value from index. 
<apex:page controller="allaccountslist">
 
     <apex:variable value="{!0}" var="rowNum"/>
     <apex:repeat value="{!accts}" var="a">
         {!a.id}............... {!accts[rowNum].name} <br/><br/>
         <apex:variable var="rowNum" value="{!rowNum + 1}"/>
     </apex:repeat>
 
</apex:page>

Option 2:- If you want to use Map then
Change your class like below :- return type should  me Map<Id,Account> 
public class allaccountslist 
{

    public Map<Id,Account> getaccts ()
    {
        Map<Id,Account> acc= new Map<Id,Account>( [select id,name from account limit 20] ) ;
        return acc;
    
    }
}

Page lik below 
<apex:page controller="allaccountslist">
 
     <apex:repeat value="{!accts}" var="a">
         {!a}............... {!accts[a].name}<br/><br/>
     </apex:repeat>
 
</apex:page>

Please let us know if this will help you

Thanks
